SILO. I

Specification of Letters Patent.

Patented May 28, I918.

Application filed March 13, 1916. Serial No. 83,839.

To all wh'om it may concern: I

Be it knownthat I, JOHN S, IIAINES, a

citizen of the United States, residing at wall structure.

I Second, to provide in a silo an improved door casing structure. w

Third, to provide in a silo an improved chute structure. I

Further objects, and objects relating to structural details willdefinitely appear from the detailed description to follow.

I accomplish theobjects ofmy invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure I is a detail front view of a structure embodying the features ofmy invention, with portions of the chute and portions of the hoopsbroken away to better disclose the structural details.

Fig. II is a detail perspective view showing one of the door casingblocks and the relation of the cross bars thereto.

Fig. III is an enlarged detail horizontal section on a linecorresponding to line 3-3 of Fig. I, showing the details of the doorcasing structure and of the chute.

Fig. IV is an enlarged detail vertical section on a line correspondingto line 4-4 of Fig. III.

Fig. V is a detail section on a line corresponding to line 55 of Fig.III.

Fig. VI is a detail horizontal section on a line corresponding to line66 of Fig. I.

Fig. VII is a diagrammatic view showing the relation of the wall blocksin the tiers and of the blocks of adjacent tiers, the tiers being shownslightly separated for clearness of illustration.

Fig. VIII is a detail section on a line corseveral views, and thesectional views are taken looking in the direction of the little arrowsat the ends of the section lines.

Referring to the drawing, 1 represents the foundation of the silo, whichis ordinarily of concrete. The wall blocks 2 and 3 are formed as rightsand lefts with rabbetlike recesses 4 at one end extending one-half thewidth of the blocks. These blocks are laid in pairs with their recessesopposed,

that is, rights and lefts are laid so that their recesses register. Theblocks are laid in the wall in tiers. The block 2, that is, one block ofeach pair is longer than the other. The

length of the blocks 2 exceeds that of the blocks 3 by the depth of therecesses 4E. The

blocks of adjacent tiers are lapped one-half their width so that thelonger blocks of one tier interlock with the recesses of the blocks ofthe adjacent tier.

The hoops 5, which are preferably in the form of flat bands, are appliedso as to engage the blocks at their tier joints. By this arrangement ofinterlocking joints the hoops effectively engage the blocks of bothtiers. If desired, the blocks may be provided with tongues and grooveson their edges, but, as such expedients are well un- I derstood, I havenot illustrated the same herein.

The door casing blocks 6 are laid in the wall with the wall blocks, thecasing blocks, however, vary in width in order to complement the wallblocks of the tiers.

The door casing blocks are provided with face plates 7 of metal. Theface plates have arm-like lugs 8 struck in therefrom and embedded in theblocks. The door casing blocks have recesses 9 at their ends, while thefacing plates have slots 10 registering with these recesses. Therecesses and slots of adjacent blocks register when in position in thewall, providing mortises for the tenons 11 of the cross bars 12. Thesecross bars are arranged with their ends abutting the face plates ofadjacent blocks and their tenons projecting into the mortises orrecesses provided therefor.

The doors are beveled at their vertical edges, as 14, to fit against theinclined shoulders 15 on the casing blocks. The casing blocks arethickened at 16 to provide these shoulders and to strengthen the blocks.The doors are clamped in position one above the other by means of'bolts17 and retaining bars 18, the bars being arranged to engage the casingblocks and clamped in place by the bolts.

1' preferably provide a chute consisting of sections 20 formed of sheetmetal and provided with edge bars or uprights 21 at their edges. Theseuprights are preferably strips of angle iron disposed with their anglesfacing inwardly. These angle bars have notches or slots 22 at their endsadapted to engage the hoops 5 so that the chute sections are eflectivelysupported. The sections are preferably arranged with their endsoverlapped, as shown in Fig. VIII. By this arrangement the chute is veryeconomical in its parts and the parts are conveniently and quicklyassembled in the erection of the silo.

The blocks of my improved silo are easily formed and may be easily laidin the wall.

Having thus described my invention, what I claim 'as new and desire tosecure by Letters Patent, is: p

1-. A wall structure of the class described comprising blocks formed asrights and lefts with rabbet-like-recesses at one end extending one-halfthe width of the blocks, said blocks being laid in tiers in coactingpairs of rights and lefts with the recesses of such pairs opposed, thelength of one block of each pair exceeding that of the other by thedepth of such recesses, the blocks of adjacent tiers being lappedone-half their width with the longer blocks of one tier interlocked inthe recesses of the blocks of the adjacent tier, and hoops disposed oversuch tier joints.

2. A wall structure of the class described comprising blocks formed asrights and lefts with rabb'et-like recesses at one end, said blocksbeing laid in tiers in coacting pairs of rights and lefts with therecesses of such pairs opposed, one block of each pair being longer thanthe other, the blocks of adjacent tiers being laid with the longerblocks of one interlocked in the recesses of the other.

3. A wall structure of the class described eompri sing blocks laid intiers, adj aeent pairs of blocks in the tiers having opposed rabbetlikerecesses, one block of each pair being longer than the other, the blocksof adjacent tiers being laid with the longer blocks of one interlockedin the recesses of the other, and

- hoops disposed over the tier joints.

In witness whereof, I have hereunto set my hand and seal inthe presenceof two witnesses.
